Hot Night With the Big Fish

Hot Night With the Big Fish Is the fifth episode of the first season of the Heaven's Lost Property.

Summary
With his house destroyed, Tomoki needs a place to stay. After Sugata's place proves to be too dangerous, Mikako offers her place to Tomoki along with Sohara, Sugata, and Ikaros. It turns out Mikako's family are influential yakuza; Ikaros momentarily scares everyone when she pets Mikako's father's head.

After dinner, Tomoki stumbles into Mikako at an outdoor bath, who casually informs him that his trespassing violates a family law, where he must be decapitated. Ikaros stops the executioner with a brief display of her power. The next morning, Tomoki finds they are on a plane to an uninhabited island as an alternative punishment instituted by Mikako. They split up to search for food and items, but Tomoki eats a mushroom and passes out. Tomoki hears yelling and rescues Sohara, but everyone else is gone, so the two spend the next few weeks enjoying island life until a sea monster grabs Sohara. Tomoki attacks the "monster," which is actually Ikaros, covered in shells and seaweed, who has returned with a big tuna.

Tomoki asks where Sugata and Mikako are; Ikaros does a scan and then knocks down a wall panel to a room where Mikako's family and Sugata have been watching them the entire time for their amusement. Later, Tomoki and Ikaros return to find his house restored, thanks to Mikako's father, who likes Ikaros and respects her power.

Trivia
